I know it's theoretically possible to cook rice from raw grains in the microwave. I may even have attempted it at some point, but I don't remember it.

I don't think reheating counts. But those shelf stable things? Amazing.

We weren't allowed any appliances other than what the dorm supplied in common areas. I kind of wish I'd pushed for a rice cooker, but I was deeply in mostly-assmilating mode then.`
